Description
The invention relates to a preparation method of a Cu-Yb nano alloy material, and the obtained Cu-Yb nano alloy material is applied to the field of catalysis, in particular to the electrocatalytic reduction of CO2The field of the technology.
Background
CO2As a greenhouseGases, the climate impact of which is slowly and significantly affecting our production and life. The urgent goals of reducing greenhouse gas emissions, reducing the harm of human activities to the climate system, and slowing down climate change, therefore, researchers have proposed using multiple methods simultaneously to mitigate global CO2Negative effects of high emissions, such as atmospheric CO2The method has the advantages of capturing and sealing, improving the energy utilization rate of vehicles and buildings, using alternative energy sources and the like. Wherein CO is introduced2The conversion of the CO into high value-added chemicals or fuels through catalytic reaction can not only realize the CO in the atmosphere2The content is reduced, and clean and environment-friendly energy can be provided, so that the environment is improved, and energy is provided. The carbon dioxide is reduced by an electrochemical method to be converted into clean energy such as CO, formic acid, methane, methanol and the like, so that not only can the problem of CO be solved2The surplus problem can also solve the problem of surplus thermal power. Moreover, the method has mild reaction conditions, does not need high temperature and high pressure, has flexible equipment operation and high energy utilization efficiency, and can regulate and control the product selectivity and the reaction speed by simply changing the electrolysis conditions, so the method is considered to be CO2The transformation technology with the most development prospect in resource utilization. But the implementation of this approach relies on the development of high performance cathodic electrocatalytic materials.
Electroreduction of CO from different metals under the same reaction conditions in a plurality of catalytic materials2The distribution of products is very different, and CO can perform multiple reaction paths due to the difference of the adsorption capacity of the reaction intermediate product CO on the surface of the reaction intermediate product CO, so that CH is generated4、CH3OH、C2H4、C2H5OH and the like. And Cu is the only metal that effectively adsorbs the intermediate CO and reduces it further to hydrocarbons. Unfortunately, there are still many problems to be solved in the current Cu-based electrocatalysts, such as: (1) high overpotential leads to low energy efficiency (CH)4Overpotential about 0.9V, C2H4Overpotential about 0.7V); (2) the electron transfer kinetics are slow; (3) the selectivity to specific products is poor, and the number of reduction products is up to 16; (4) the bias current density is too low; (5) catalytic converterThe stability of the agent is poor and the agent is generally inactivated within 1 to 5 hours. The above problems severely limit the commercial application of Cu-based catalytic materials. Based on the above, researchers optimize the Cu-based electrocatalyst in terms of size, morphology, composition, surface ligands, and other structures to improve its catalytic performance. Research shows that compared with a single metal catalyst, the alloy catalyst is flexible in design, various in types and various in structure, often shows more excellent catalytic performance than the single metal forming the alloy catalyst, and is favored by researchers in the field of energy catalysis. In CO2In the electrocatalytic reduction reaction, the structure and the components of the catalyst are changed in the alloying process so as to regulate and control the binding energy of a reaction intermediate on the surface of the catalyst and break the linear relation existing between intermediate products, thereby achieving the purposes of reducing reaction overpotential and improving the selectivity of a specific product.
In combination with the current situation, the invention aims at overcoming the defects of high overpotential of reaction, low product selectivity, poor catalytic stability and the like of the Cu-based catalyst and aims at improving the electrocatalytic reduction of CO by optimizing the structure and the composition of the Cu-based catalyst2And (6) performing.
